| 167808 | 2003-08-21 10:39:00 | ive got a Duron 1.3Ghz that goes from 46-53 but it does have a volcano 9 on full power on it - Durons are overheaters, but the athlon should be cooler, if its a new one | agent_24 (4330) | ||
| 167809 | 2003-08-22 05:16:00 | i just installed MotherBoard Monitor 5 on my compuer i set my sensor on LM90 Local it gave results that looked like the cpu temperature but now instead of the 54 or 55C from the health status in bios it is showing around 37C is there a way to test which reading is correct? or closer to the actual value 55 and 37 is a big difference... |

| 167810 | 2003-08-22 05:24:00 | Open the lid and put your finger on the heatsink. If it feels "just warm" it will be a bit over 30° C. If it feels hot, it will be nearer 60°C. If you can bear your finger on it for only a second, that's 70°. If it raises a blister, it's hot. | Graham L (2) | ||
| 167811 | 2003-08-22 05:39:00 | If it glows..it's way too hot :) | Pheonix (280) | ||
| 167812 | 2003-08-22 08:09:00 | um.. isn't the fan above the heat sink... how exactly do i put my finger on the heat sink? and lucky..no .. it doesn't glow... |

| 167813 | 2003-08-22 08:14:00 | ..i touched the side... couldn't really feel much heat at all... just slightly warmer than my finger,, |

| 167815 | 2003-08-23 03:45:00 | You touched the side of the heatsink ... that's fine; behave yourself Susan :O. It was "warm" ... that's somewhere in the 30s. That's fine. The "measurements" made by the hardware are no more accurate than what you've just done. The thermister and the simple A-D conversion gives an indication. It might cost 20 or 30 cents to put a proper temperature sensor on the motherboard. :D The actual temperature inside the chip would be interesting to know ... it would be considerably higher: a couple of datasheets for Mosfets I have on my desk right now show maximum allowable Junction temperature as 175°C, and the thermal resistance Junction-Ambient of 62.5°C/W. :D How many watts do these modern CPUs dissipate? That Mosfet figure is for the unit without heatsink ... and the usual mode is hard on and hard off, so there's virtually no dissipation. In fact I've just used my digital calculator -- fingers -- to work out that an STP30NE06L dissipates 1.5W at maximum current of 30A, so it would get the junction 93°C above ambient, so I think I'd use a heatsink if I was working it that hard. :D |

| 167816 | 2003-08-23 04:33:00 | I have an Athlon XP 2000+ (Family 6, Model 8, Stepping 0) and I'm using cheap DSE thermal grease with two fans running (one exhaust, one intake) and my one runs at 47 degrees Celsius (according to Gigabyte EasyTune 4) under full load, so yours should be a fair bit cooler if you have extra fans in your case. | wintertide (1306) | ||
